Abstract
Transcatheter arterial chemoembolization with drug-eluting beads (TACE-DC-beads) is a new local treatment for primary or metastatic liver tumors. Despite technical efforts to achieve highly selective embolization of the tumor-supplying vessels, small, or large insults to the non-tumorous parenchyma are inevitably induced by the embolic materials or procedure itself. Parenchymal changes following TACE-DC-beads include bile duct injuries (bile duct dilatation, periportal edema, and bilomas), obliteration of intrahepatic portal vein branches, hypodense ill-defined areas, and perilesional parenchymal enhancement. The radiologist must be familiar with the changes induced by this treatment in order to distinguish therapeutic effect and collateral findings from complications and residual or recurrent tumor.
